Windows 7: Unable to connect to internet, virus deleted my drivers

Unable to connect to internet, virus deleted my drivers

Hi everyone! My laptop, Lenovo T420, got infected by a nasty virus. Though I've deleted the virus, but it already deleted several drivers for my computer: ethernet controller, biometric coprocessor, and video controller (which I checked through 'Device Manager' saying: "No drivers are installed for this device") I've installed back the driver for my ethernet controller and wireless network drivers from Lenovo website. But still unable to see any wifi connection even though there are several open.

When I open "Network and Sharing Center" it says that "The dependency service or group failed to start." When I check "System Information" (through msinfo32) and click "Problem Devices" it says that there is an error in: "TCP/IP Registry Compatibility" and "WAN Miniport (L2TP)".

When I open "Network Connections", my "Broadband Connection" is Disconnected and has "Error 1060: The specified service does not exist as an installed service."

Furthermore, I also cannot turn on windows firewall. The screen resolution is also changed and I'm unable to revert it back to the original although I've tried tinkering with the "Adjust screen resolution". What shall I do to fix my internet, firewall, and screen resolution? Any help is much appreciated.

Hi and Welcome to the Forum bori02082005 You can download the Wan driver from the Lenovo site Where you using Windows Firewall before you had detected the Virus ? Having an Lenvo you should have the One Key Recovery Option.

Hi Maxie. Thanks for the reply. I've downloaded the WAN driver from Lenovo. But I still had the same status as before. As for the One Key Recovery Option, I don't have the program when I looked it up.

Where you using the Firewall before you had these problems?

If you get no love with the sfc/scannow, which I too recommend, then a repair install may be in your future. If not a complete clean install. We have many fine tutorials here, written by some very knowledgeable people. I highly suggest you avail yourself to them.

Here is the SFC/SCANNOW result. Not sure about the firewall because I never checked it. I just checked it recently.

Are you using any other AV like McAfee?
